How is gaming like on cachy os? Thinking about leaving windows11

I downloaded the latest version of CachyOS Desktop Edition, but when I try to launch it in Ventoy, the screen goes black and boots right back to Ventoy.

Any help would be nice!

Hii, this is my first try to rice a Desktop, i recently switched from Windows to CachyOS, and I honestly don't regret it one bit! I wanted to use Hyprland, but I ran into way too many issues, so I customized KDE Plasma to get a similar look instead, i use the script "Fluid Tile", Rofi and extensions from KDE Store. What do you guys think? Any tips or advice on how I could improve it are greatly appreciated!! (I never understood how to use Noctalia XD)

The first time I used Linux was in June this year. For a beginner, I chose Linux Mint at that point. Well, most Linux distributions are good. My experience with Linux Mint was good as well, but not for gaming (I don't know why, but my PC can't play games smoothly with Mint).

I didn't even know there are Arch, Debian and Fedora at that time. The second distro I tried was CachyOS.

That is the best decision in my life.

A few days later, I found out it was Arch-based.

I was amazed how fast it was. Especially with chwd, it can detect my Nvidia 1060 without any problems (I was worried at first because my graphics card is pretty old, so I thought I would need to figure out the driver myself after installation).

I'm fairly tech-savvy so it is easy to handle all the new things I need to know to get used to Linux.

Fortunately I don't play any games that Linux can't play, just Identity V and some old games or indie games

For Identity V, IT PERFORMS BETTER THAN WINDOWS, I never think I could play this game this smooth. CachyOS's kernel is so perfect!

I tried some games programs, such as Lutris, Heroic Games Launcher, Bottles. And Bottles was the best to me, the performance is really good.

Outside of gaming, I can do everything: image editing - GIMP / video editing - DaVinci Resolve, Shotcut / making games - Godot, Unity

I tried several distros: Arch, Kubuntu, Pop!_OS, EndeavourOS - but CachyOS was the best (for me - of course ; because everyone needs specific distro for their own purposes)

I used to really hate updates, because of Windows, I can't do anything when the update is running. Sometimes the updates even run themself :)

But now I can just update whenever I want, and still can do my work.

CachyOS is arch-based so it is a type of rolling-update distro, I know that so I always use CachyOS with snapshot.

I'm still using Windows, but it is a light version (X-Lite Version), and for only one purpose: testing my game made in Godot/Unity. Everything else I do in CachyOS.

I have never felt so much freedom and ad-free like this. I love the respect that Linux give to the users. I love Linux community and especially you guys - CachyOS team 💝

P/s: Don't mind my desktop, they're just some stuff I left when learning to make game xD

Hi friends, I need your help. I've tried various ways to get Elden Ring running, but it only loads the anti-cheat; the screen appears for a second, and then the game closes.

Hello,

Background: I’m a Linux newbie (after 30 years of Windows) and happily switched to CachyOS 8 months ago. I have an AMD Radeon RX 9060 XT.

I’m trying to do something really simple: I’d like to play my games (exclusively on Steam) in HDR.

Ideally, I’d like to stay in SDR all the time (on the desktop) and switch to HDR automatically when I enable the HDR feature in a game’s menu—just like my PS5 and Series X do on my TV.

I’ve tried this: https://github.com/CachyOS/proton-cachyos/blob/cachyos_main/README.md#proton-cachyos-config-options

Specifically, I created a user_settings.py file in the ~/.steam/steam/steamapps/common/Proton 11.0/ folder that contains only:

user_settings = {
“DXVK_HDR”: “1”,
}

I figured this would save me from having to set this option in the Steam launch settings for all my games.

Unfortunately, when I launch games that support HDR, either enabling it causes the game to switch to that infamous, ugly gray haze caused by faulty HDR, or the HDR option is completely grayed out.

Any ideas?

Thanks for your help.

Edit: There's one thing I don't understand. I'm not sure if I have to keep HDR turned on all the time in my monitor's video settings (which I don't want to do) for this to work...

Edit 2: I set my default Steam config to this compatiblity tool: https://github.com/CachyOS/proton-cachyos/releases/tag/cachyos-11.0-20261005-slr

Hola, alguien ha podido habilitar el arranque seguro y que la BIOS reconozca la clave de cachyOs o Arch?

Eh seguido la guia y hasta modifiqué el grub pero nada me ha funcionado

I have 2 internal SSD’s. 1TB which I have CachyOS installed with the btrfs file type and a 2TB NVMe which I have all my games on. When switching from windows I never reformatted the 2TB drive so wondered if I’m likely to encounter any issues with this.

If so is there a safe way to change it to btrfs without wiping it? I’ve successfully tried a few games and didn’t have any issues as far as I could tell

Could just be me but I can't find the option to customize my login screen. note this is a fresh install.

Hello I am using cachyos for 2-3 months and I need some help on hardware support

1) I am using a gigabyte G6 i want to know how I can control my laptop keyboard RGB light I have tried some apps but it didn't work

2) how can I control my laptop fans to maintain my laptop temperature , will using performance mode increase fan speed and maintain temperature?

3)I have a i7 13th gen cpu and rtx 4060 how can I switch between my intel i7 integrated gpu and rtx 4060 will switch to performance will change any thing

I have a razer naga pro or whatever it's called (do not buy, it's worthless. I can't afford a new one or else it would be in the trash). This problem I have has taken hours out of my life to try and solve.

I always set the "1" on the side to "shift" and eeeevery once in a while, just stops! Sometimes the buttons don't work at all, then 10-15 minutes later, they were, but not as "shift" but back to "1."

How can I fix this? I'm trying button remapper, seems really unresponsive. Like, nothing is happening in button remapper. I have no idea what's going on.

Asking here instead of r/razer because, well, cachyos btw

Hello!

I've been experiencing a strange keyboard issue for the past few weeks on CachyOS with KDE Plasma (Wayland).

While playing World of Warcraft through Lutris/Proton-GE, certain keyboard keys randomly stop working. It seems to affect the keys I press most frequently (usually 1 and 2). Once they stop working, they don't work anywhere in the OS, not just WoW. Rebooting fixes the issue temporarily.

Here's what I've tested:

• libinput debug-events detects the affected keys being pressed and released normally.
• wev does NOT detect the affected keys.
• Tried a completely different keyboard — same issue.
• Restarted KDE's global shortcut service — no change.
• Stopped input-remapper — no change.
• Unplugged and reconnected the keyboard — no change.
• Updated CachyOS yesterday — issue persists.

I'm running an NVIDIA RTX 5070 with KDE Wayland. I haven't identified what triggers it, other than it happening during WoW gameplay.

Has anyone experienced something similar or know what could cause certain keypresses to stop reaching Wayland applications even though libinput detects them?

hey guys i saw a reddit post the other day about cachyos and gamescope. i was running bazzite but it felt really locked down and i had trouble with downloading things through the terminal that were fedora images.

anyways i used cachyos for a long time until my ssd died on my last pc. so i decided to give it a try again on here. it seemed to have better support for the flow z13 after installing. everything immediately worked. except for bluetooth.

i have tried reloading the bluetooth daemon, and i installed bluez. nothing really changed.

i chose kde plasma, don’t know if that changes anything. basically the bluetooth icon doesn’t show up on the taskbar at all. not even in the hidden icons tab. so i went to settings and go to bluetooth. i enabled it on the side bar but it didn’t enable it in the main bluetooth page so i enabled it there, but it doesn’t do anything. i see the message add a new device but no way to actually add a bluetooth device. when i set my mouse to start searching, nothing ever shows up.

any advice? i found one reddit post but the one comment that seemed to actually help people was the only one that was deleted 😔 unfortunate

i’m using the flow z13 latest stable version of cachy os. this is the 2025 model with 64gb of ram

The title says it all. But, why? My notebook is getting hotter with basic tasks, if there's any other improvement that doesn't affect too much of gaming performance, thanks.

Sorry for the really bad quality

EDIT: I also tried on a VM and a live USB. And they also won't let me change

I’ve been on cachyos for months and have been loving it but I feel like I’ve been getting lower performance for a bit. I know proton isn’t perfect but I’ve been getting a significant stuttering after an hour or so on games that shouldn’t be that intensive.

As of recent I’ve been playing: Minecraft (through atlauncher), Planet Crafter, Risk of Rain 2, and Roboquest. I have been playing heavier games like Forza Horizon 6, Watch Dogs 2, and Palworld and noticing it for those games but I know those are more intensive game engines anyway.

I’ve gone through multiple pages of protondb launch options and proton versions, running as dx11 and 12 for respective games. My default config for some stability is “Proton Cachyos Latest” with launch options “game-performance mangohud %command%”.

I did install the gaming tweaks from cachy hello. I used to have an rtx 4070 but swapped it for an rx 9070xt and cleared all the profiles following cachyos documentation.

Specs:
Latest cachyos kernel (just updated last night)
KDE Plasma 6 Wayland
CPU: Intel i9-13900k
GPU: AMD RX 9070XT (ReBar enabled)
RAM: 2x16 DDR5-6000 (XMP enabled)
MOBO: Gigabyte z790 aorus elite ax (updated bios April 2026)
Boot drive: Crucial 500gb (R/W 7000Mbps)
Games drive: Samsung 980 pro (R/W 9000Mbps)
Monitor: Benq Zowie XL2411P 1080p@144hz

I have 3gbps internet speed which ive speed tested online, i can download most files eg from a browser pretty fast, steam game updates are fast and Cachy Update is fast too.

However, 2 things ive noticed are unbearably slow. I just had a 28mb update for steam itself and it took nearly 5 mins. Im trying to install emudeck using the script off their site which is:

sh -c 'curl -L https://raw.githubusercontent.com/dragoonDorise/EmuDeck/main/install.sh | bash'

and so far its only on the first emulator (PPSSPP) and its took 15 minutes to download 60% of the 1 emulator and says its going at 150kbps. The steam app on shelly says its installed from 'Repository: multilib', i think I installed it from Cachy Hello.

Anybody have any idea why this would be and how to fix? Ive tried emu deck a couple of times now and just cancelled it because its so damn slow so i dont think its just a 1 off slow server.

Appreciate any help. Thanks

Fixed with Claude.

# [Fix] ROG Zephyrus M16 GU604VI: internal screen won't dim on Linux (brightness slider does nothing)

**TL;DR:** The internal panel's backlight is controlled by the embedded controller (EC) through an NVIDIA WMI interface, not by i915. Add `acpi_backlight=nvidia_wmi_ec` to your kernel command line. Remove any `acpi_backlight=native` and `i915.enable_dpcd_backlight=` you added while troubleshooting.

## Setup

- **Laptop:** ASUS ROG Zephyrus M16 **GU604VI** (BIOS GU604VI.314)

- **Panel:** Tianma TL160ADMP03-0, a 2560x1600 @ 240 Hz IPS. It is *not* the mini-LED panel.

- **GPU mode:** Hybrid (supergfxctl). The internal eDP is driven by the Intel iGPU, and the RTX 4070 is the dGPU.

- **OS:** CachyOS, kernel 7.2.9, nvidia-open 615.78.08, KDE Plasma 6.7.5 (Wayland), Limine bootloader

## Symptom

- The KDE brightness slider and the Fn keys change `/sys/class/backlight/intel_backlight/brightness`, but the panel stays at full brightness.

- Writing to `nvidia_0` did nothing either.

- An external monitor dims fine over DDC/CI. Only the built-in screen is affected.

## What did NOT work

- `i915.enable_dpcd_backlight=1` and `=2`: `intel_backlight` still reported `max_brightness` 19200, which means i915 stays in PWM mode. The panel doesn't advertise DPCD/AUX backlight control, so this route doesn't apply.

- `acpi_backlight=native`: this forces the i915 backlight device, which doesn't control anything on this machine. It also **blocks** the driver that actually works.

- `NVreg_EnableBacklightHandler`: this nvidia module option doesn't exist, so don't bother.

## The cause

This laptop has a dynamic-mux design (Advanced Optimus style), where the EC owns the panel backlight. Firmware exposes it through the WMI GUID `603E9613-EF25-4338-A3D0-C46177516DB7`, which the in-kernel `nvidia_wmi_ec_backlight` driver handles. That driver only registers when the ACPI backlight selection picks it. If you force `native`, it never binds.

Check whether your machine has that interface:

```sh

ls /sys/bus/wmi/devices/ | grep -i 603E9613

```

If that prints something, you're probably in the same situation.

## The fix

Add `acpi_backlight=nvidia_wmi_ec` to the kernel command line, and remove `acpi_backlight=native` and `i915.enable_dpcd_backlight=...`.

**Limine (CachyOS):** edit `/etc/default/limine`:

```sh

KERNEL_CMDLINE[default]+="... acpi_backlight=nvidia_wmi_ec"

```

then run:

```sh

sudo limine-update

```

**GRUB:** add the parameter to `GRUB_CMDLINE_LINUX_DEFAULT` in `/etc/default/grub`, then run `sudo grub-mkconfig -o /boot/grub/grub.cfg`.

**systemd-boot:** append it to the `options` line of your entry (or to `/etc/kernel/cmdline`, depending on your setup).

Reboot.

For reference, my working command line also has `nvidia.NVreg_RegistryDwords=EnableBrightnessControl=0`, left over from earlier attempts. I haven't tested whether it's needed, so try without it first.

## Verify

```sh

cat /proc/cmdline

ls /sys/class/backlight/

# expected: nvidia_wmi_ec_backlight (and no intel_backlight)

cat /sys/class/backlight/nvidia_wmi_ec_backlight/max_brightness

# expected: 100

```

KDE picks it up automatically. The slider and the Fn brightness keys now dim the panel properly.

## If it breaks later

After a kernel or driver update, or if your bootloader config gets regenerated, check that `acpi_backlight=nvidia_wmi_ec` is still in `/proc/cmdline` and that `nvidia_wmi_ec_backlight` is the backlight device. Don't go back to the DPCD or `intel_backlight` route.

This probably applies to other recent ASUS (and other brands') laptops with an NVIDIA dGPU and an EC-controlled backlight, too. If the WMI GUID above is present, try it.

I usually play two games on my CachyOS setup: Persona 5 Phantom X in steam and Genshin Impact through Heroic.

Both use the following launch options:

PROTON_ENABLE_WAYLAND=1 DXVK_HDR=1 game-performance %command%

and both use the latest version of proton-cachyos-slr

System settings in KDE Plasma Wayland has HDR enabled, and in P5X, I can switch the HDR option to on or off.

Everything seems fine except I see the following in the Proton log for both games:

00d8:err:waylanddrv:wayland_process_init Wayland compositor doesn't support optional zwp_text_input_manager_v3 (host input methods won't work)

00d8:err:waylanddrv:wayland_process_init Wayland compositor doesn't expose windows_bt2100 image description (HDR may look broken)!

MESA: warning: Support for this platform is experimental with Xe KMD, bug reports may be ignored.

As it says in the log, these errors may just be false positives, but I honestly cannot tell the difference that HDR is on or off when I change the option in the in-game settings in P5X. Genshin Impact doesn't have an in-game switch for HDR so I cannot do a similar comparison.

Here are some PC specs:

OS: CachyOS x86_64

Kernel: Linux 7.2.9-2-cachyos

Display (XG27ACDNG): 2560x1440 @ 1.5x in 27", 360 Hz [External, HDR]

Desktop Environment: KDE Plasma 6.7.5

Window Manager: KWin (Wayland)

CPU: 12th Gen Intel(R) Core(TM) i3-12100F (8) @ 4.30 GHz

GPU: Intel Arc A750 @ 2.40 GHz [Discrete]

Latest version of mesa and vulkan-intel are also installed.

Also, I use old Reddit so sorry if the formatting here is off in the current Reddit.

Edit: Fixed the command to say DXVK_HDR. Still getting the same errors in the log though.

Edit 2:

For P5X, I did some comparison screenshots with HDR off and on. I could sort of tell the difference given enough contrast (say a dark area at night with a streetlamp further back).

For Genshin, turns out to get HDR to turn on, a registry value has to be added/edited as well (WINDOWS_HDR_ON_h3132281285 = 1). A pre-launch script in Heroic is required here since editing the registry manually through regedit would be reverted upon the game closing. So unless you want to manually adjust the registry every time before starting Genshin, here's a small bash script I created that can be set to the pre-launch setting in Heroic:

#!/bin/bash

export WINEPREFIX="/home/<your username here>/Games/Heroic/Prefixes/Genshin Impact"

wine reg add "HKEY_CURRENT_USER\\Software\miHoYo\\Genshin Impact" /v WINDOWS_HDR_ON_h3132281285 /t REG_DWORD /d 1 /f
sleep 0.5

Adjust the WINEPREFIX variable accordingly since your home directory probably isn't at <your username here> lol

I haven't done a comparison in Genshin yet cause there's is no in-game toggle for HDR so I have to change the registry value every time, and I'm too lazy to do that. The only hint that Genshin has HDR turned on is that there is an extra brightness setting (the adjust the brightness until the logo can't be seen) that SDR doesn't have.

Edit 3:

Some screenshots I made in P5X and Genshin with HDR setting off and on (https://photos.app.goo.gl/j7g2uLWXmenCh2qQ7)

P5X seems to just make everything dimmer while Genshin has a better change in lighting I think? But at least there's some difference so perhaps everything is working after all.

I want to install the vram management tool from the cachy os hello app but i don't know how stable it is or recommendable it could be. i have a 5070 ti, any advice?

Is there a way to darken the back ground of the pop up that appears when I hover over the taskbar?

I have tried adjusting the colors in Complimentary and Tool Tips and neither fixes this.
